Low‐Temperature Mesoscopic Mechanical Damage of AP/Al/HTPB Composite Propellants

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
To investigate the mechanical damage of solid propellants under low‐temperature conditions, an equivalent modeling approach was employed to establish a mesoscopic particle–embedded model of the hydroxyl‐terminated polybutadiene (HTPB) propellant. Uniaxial tensile numerical simulations were conducted on the propellant under varying strain rates and ...

Coating of High Melting Explosive Particles by Nitrotriazolone to Formulate Composite Nanoparticles by Spray Flash Evaporation

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 32-39, December 2025.
ABSTRACT The balance between performance and safety of high explosives is at the heart of the current studies, and new ways of combining safety and performance have hence been elaborated. This study focuses on a mixture of 3‐nitro‐1,2,4‐triazol‐5‐one (NTO) and octogen (high melting explosive [HMX]).
